XR5FC/XR5SL Installation Guide

Keypad Data Bus

9.1 Description

Terminals 7, 8, 9, and 10 of the XR5FC and XR5SL panels provide the keypad data bus to which you can

connect Model 692F LED keypads as well as two alphanumeric Security Command keypads.

9.2 Terminal 7 - RED

Terminal 7 provides 12 VDC keypad power for Security Command keypads. You can also connect 12 VDC

auxiliary devices to terminal 7. The ground reference for terminal 7 is terminal 10. The maximum output is rated

at 500mA on the XR5FC and XR5SL panels. All auxiliary devices totalled together must not exceed the panel's

maximum current rating.

9.3 Terminal 8 - YELLOW

Data receive from keypads.

9.4 Terminal 9 - GREEN

Data transmit to keypads.

9.5 Terminal 10 - BLACK

Terminal 10 is the ground reference for keypads and any auxiliary devices being powered by terminal 7.

Class A (Style D) Fire Zone

10.1 Description

Terminals 11 to 14 are the panel's Class A (Style D) fire zone. This zone is suitable for connecting waterflow

devices, heat detectors, and other non-powered fire devices. For programming purposes, this is zone number 1.

The zone is rated for 1.66mA at 5.0 VDC.

The zone configuration on terminals 11 to 14 are described below.

Terminal Function Terminal Function

11 Zone 1 voltage sensing 12 Negative for terminal 11

13 Zone 1 voltage sensing 14 Negative for terminal 13

The voltage sensing terminal measures the voltage flowing through the circuit to the zone's negative terminal.

Dry contact sensing devices can be used only in parallel (normally-open) with zone 1. There are no End of Line

resistors on a Class A (Style D) zone.

Class B (Style A) Fire Zones

11.1 Description

Terminals 15 to 22 are the Class B (Style A) fire zones on the XR5FC and XR5SL panels. These zones are

suitable for connecting powered or non-powered fire devices. For programming purposes, these zones are

designated 2 to 5. The zone configurations on terminals 15 to 22 are described below:

Terminal Function Terminal Function

15 Zone 2 voltage sensing 16 Zone 2 negative

17 Zone 3 voltage sensing 18 Zone 3 negative

19 Zone 4 voltage sensing 20 Zone 4 negative

21 Zone 5 voltage sensing 22 Zone 5 negative

11.2 Operational parameters

The Class B (Style A) zones on the XR5FC and XR5SL panels can detect three conditions: open, normal, and

short. Each zone terminates with a Model 309, 3.3k Ω EOL resistor (provided with the panel) and is rated for

53mA at 12 VDC.

The UL compatibility identifier for use with 2-wire smoke detectors is: A.
